StriVectin Advanced Acids Hyaluronic Dual-Response Serum 30ml is a clever two-chamber serum designed to deliver immediate plumping hydration and longer-term moisture protection in a single product. Six forms of hyaluronic acid in one chamber, paired with StriVectin's patented NIA-114 and a ceramide blend in the other, work together to refill, smooth and reinforce dehydrated skin.
About StriVectin
StriVectin is an American science-led skincare brand whose modern identity revolves around its patented NIA-114 molecule — a stabilised form of niacin shown to support the dermal barrier and amplify the effects of other actives. The Advanced Acids line is the brand's hero hydration collection, with the Dual-Response Serum as its most concentrated moisture-targeting treatment.
Key ingredients
- Six forms of Hyaluronic Acid: short-chain, long-chain, cross-linked and standard hyaluronate — multi-weight hydration at different depths.
- NIA-114 (3-O-Ethyl Niacin): StriVectin's patented active that supports the skin barrier and boosts the efficacy of other ingredients.
- Ceramide NP, AP, EOP: a multi-ceramide blend that helps reinforce the lipid barrier.
- Phytosphingosine: supports the skin's natural protective lipids.
- Acetyl Hexapeptide-37: a peptide active for additional smoothing.
- Apple (Pyrus Malus) Fruit Extract: additional antioxidant support.
- Vitamin E (Tocopherol Acetate): antioxidant defence.
Key benefits
- Delivers immediate plumping hydration and longer-lasting moisture retention from one serum.
- Helps reinforce the skin's natural barrier, reducing moisture loss.
- Smooths the appearance of fine dehydration lines.
- Layers easily under makeup and works alongside richer night treatments.
- Clever two-chamber design that mixes the two phases as you dispense.
Who it's for
This dual-response serum is designed for anyone whose main concern is dehydration, dullness or a compromised skin barrier — particularly those who travel often, work in air-conditioned environments or experience tight, dehydrated skin after using active treatments. Suitable across most skin types, including sensitive complexions thanks to the barrier-supporting ceramides.
How to use
- Cleanse and tone the skin in the morning and evening.
- Hold the dispenser horizontally and press the pump — the formula combines both chambers as it dispenses.
- Smooth gently over face and neck, working outwards from the centre.
- Follow with your usual moisturiser. In the morning, finish with a broad-spectrum sunscreen.
